TIMOTHY J. KIELEY, OF NE\V YORK, N. Y.

GAS-REGULATOR FOR BOiLERS.

SPECIFICATION forming part of Letters Patent No. 359,079, dated March 8,1867.

Application filed January 11, 1887. Serial No.22-1,018. (No model.)

To all whom it may concern.-

Be it known that I, TIMOTHY J. KIELEY, of the city, county, and State of New York, have invented a new and useful Improvement in Gas-Regulators for Boilers, of which the followingis a full, true, and exact description, reference being had to the accompanying drawings.

Since the introduction of natural gas it has been common to heat boilers by such combustion. WVhen gas is burned beneath aboiler, a ready means is afforded {for controlling the steam-pressure in the said boiler by means of the combination which Ihave herein described. By this arrangement the steam-pressure in the boiler determines the amount of gas to be burned.

In my drawings, Figure 1 represents an external view of my apparatus; Fig. 2, a crosssection' of the same, Fig. 3, a cross-section of a modification, showing a double instead of a Single valve.

My apparatus consists,generally,of two diaphragm-chambers, A and B, controlling a valve within the valve-chamber O. In the form shown in Fig. 2, this is a single puppet-valve. In the form shown in Fig. 3 a double valve is employed. The operation isidentical. I prefer, generally, to employ a single valve, as it is tighter. Such valve is lettered D. The valve D, whether single or double, is controlled by the valve-stem E, which is fastened at its up per end to the diaphragm F. The valve-stem is continued through the diaphragm and connects by the stem or connector G with the le ver H, pivoted in the standard K. A stem, L, likewise connects said lever H with a second diaphragm, M. The lower surface ofthis diphragm connects with the pipe, N which is connected to the boiler-pressure. I have not explained the construction of these regulating diaphragms in detail, as they are well known in the art.

The gas to be consumed enters the valveboX Gby the inlet 0, and leaves it bythe out let 1, its passage being regulated by the valve D. In Fig. l is shown anarrangement by which the inlethnay be either at the bottom or side of the valve-chest by simply moving the plug from one side to the other, thus enabling the same casting to serve as an angle or straight-way valve. In the form shown in Fig. 3 it will be observed that the relation of the diaphragm to the lever and the method of seating of the valve are somewhat different. In Fig. 2 the valve-stein is on one side of the pivot and the regulatirig-diaphragm on the other. ver is, first, the pivot, then, the regulatingdiaphragm, and then the valve-stem. This arrangement gives me a greater motion on my Valve, and I prefer it for most arrangements. In this arrangement, as will be observed, the valves seat upward, whereas in the form shown in Fig. 2 the valve seats downward.

The operation of my apparatus is evident. Steam-pressure entering through the pipe N controls the position of the lever H, and when it is sufficient to overcome the weight of the counter-balance \V the lever I-I rises, thereby closing, or partially closing, the valveD. It is obvious that by my arrangement of the second diaphragm all stuffing'boxes are avoided; and stuffing-boxes in a contrivance of this kind are a great disadvantage, because the varying resistance of suchstufiing-box necessarily varies the regulation of the apparatus.

I am aware that it is not new to control the supply of gas to a generator through the me dium of a diaphragm which is acted upon by pressure from said generator, and I therefore do not broadly claim such a device.

\Vhat I claim as n'iyinvention, and desire to secure by Letters Patent, is

1. In a gas-regulator, a chamber in communication with a valve-casing, and a diaphragm within said chamber connected to a "alve within said casing, in combination with a second chamber in communication with a generator, a diaphragm within said second chamher, and connections, substantially as described, between said diaphragms, whereby an increase of pressure in said generator simultaneously moves said diaphragms in opposite directions to close the valve, as and for the purpose set forth.

2. In a gas-regulator, a chamber communicating with a casing interposed in a gas-supply pipe, a valve within said casing controlling the iiow of fluid through said pipe, and connections between said valve and a diaphragm, covering said chamber, in combination with a second chamberin communication In Fig. 3 the arrangement on the lewith a generator, a diaphragm covering said latter chamber, controlled by the pressure in said generator, a positive connection between said diaphragms, and a regulatingweight to vary the resistance to the movements of said diaphragms and valve, as and for the purpose set forth.

3. In a gas-regulator, the combinaliomwith a valve, its casing, a chamber in communica tion with said casing, and a diaphragm covering said chamber connected with said valve, of a second chamber in communication with a generator, a diaphragm in position to receive pressure from said generator, a lever connected to said diaphragms, and provided with an adj ustable weight to regulate the degree of pressu re necessary to move the valve, substantially as described.

4. The within-described combination, with a diaphragm, M, of a valve, D, lever H, connected both to said diaphragm and to said valve, a chamber below the diaphragm, and a connection between the said chamber and a generator, substantially as described.

5. The combination of a casing containing a diaphragm, M, and chamber below the same, a pipe, N, communicating with said chamber and with a steam-generator, a diaphragm, F, counterbalanced lever H, pivoted intermediate of said diaphragms to a rigid support, K, connections L and G between said lever and said diaphragms, and regulating-valve D, connected with the diaphragm F, to regulate and control the passage of gas through valve-chamber C, substantially as described.

In testimony whereofI havesigned my name to this specification in the presence of two subscribing witnesses.

TIMOTHY J. KIELEY.
